JOHN B. REIMUND AND JOSEPH W. KYLE, OF CHICAGO ILLINOlSy SAID KYLE ASSIGNOR TO SAID REIMUND.

OIL-CUP.

To all whom it may concern:

Be it known that we. JoHN B. Rumour) and JosEPH \Y. hvtn. citizens of the United States, and residents of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Cups; and we do herebydeclare that the following is a full. clear. and exact description of the same. reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. i

This invention relates to improvements in oil cups of that class adapted for attachment to a rotative element such as a loose pulley.

Various devices have been employed to lubricate 1 5 loose pulleys, idler pulleys and the like and though these have been more or less successful for the purpose for which designed they have sometimes been subject to serious defects. The cups have been difficult to fill. It has been impossible to sufficiently lubricate the bearing owing to the centrifugal tendency of the oil in' the cup. It has been .diflicult to regulate the feed from the cup inasmuch as the oil or lubricant becomes somewhat more fluid even under a slight increase in temperature due to the operation of the pulley and in 2 consequence the feed has usually been somewhatirregular. i

The objectof this invention is to provide an oiler of the class described in which the cup can be easily filled independently of the position of the wheel and in which the feed of the oil iseffected mainly at the intervals when the pulley is at rest.

It is also an object of the invention to afford a construction in which the centrifugal tendency of the lubricant insures the delivery to the bearing of a charge of the lubricant when the pulley or element carrying the lubricating cup comes to rest.

It is further an object of the invention to provide a cheap simple and durable construption not likely to get out of repair. I

40 The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

1n the drawings: Figure 1 is a side elevation of a loose pulley provided with an oil cup embodying my invention. Fig. 2 is a side elevation of the oil cup. Fig. 3 is a central vertical section of the same. Fig. 4 is a section taken on line 44 of Fig. 3. Fig. 5 is a section taken on line 55 of Fig. 3. As shown in said drawings: A indicates the shaft and l3 a loose pulley or any rotative element on said shaft.

Secured in the hub of said pulley and opening therethrough to the shaft A; is thlubricator cup D. This as shown comprises a tubular nipple C, threaded at its lower end to engage in the oil aperture in said hub which is also threaded and its upper end, in which is Specification of Letters Patent.

an axial bore of larger size, is angular to permit engagement by a wrench and secured on opposite sides thereof are oppositely directed, alined pins or arms 0. Secured on said nipple is the cup proper. This comprises a cylindric, metallic shell D conically tapered and closed at its upper end and constructed as shown of pressed steel or other suitable material. Pressed or otherwise secured in said cup to afford a tight joint is a peripherally flanged plate d which affords the bottom and is provided with a central aperture therethrou gh surrounded by a peripheral flange d and through which extends a tube d of considerable size. Said tube is of a length to extend to the top of the cup and to project through the bottom d, thereof a distance equal to the depth of the larger bore in the nipple G. Said tube d", is notched at its upper end to communicate with the interior of the cup near the apex of the conical top. Said cup is provided in its margin which extends below the bottom d with oppositely disposed notches c in the manner of lamp sockets to receive the pins or arms 0 as 7 shown in Figs. 2 and 3 so that said cup when forced downwardly over the nipple by slight rotations thereon is rigidly secured in place. As shown a small vent aperture d is provided in the bottom plate (1 of the cup in position to be covered by the top of the nipple G when said cup is secured in place.

The operation is as follows: The nipple is secured in the hub as before described and the cup is removed and inverted and the desired quantity of oil or lubricant is poured therein through the tube d the air being displaced from said cup through the vent hole in the bottom. The cup can thus be very easily filled and its contents cannot spill. When inserted over the nipple, with the end of the tube d inserted in the larger bore in said nipple, a slight rotation of the cur) thereon secures the same firmly in place. When the pulley is brought into operation the centrifugal tendency caused by the rotation thereof throws the lubricant to the apex of the cup forcing the same into and filling the tube and carrying a small quantity thereof through the passage in the nipple to the bearing ,However the principal lubricating action is preferably secured by relying upon the lubrication ensuing after the wheel has stopped its rotation. For this purpose one or more of said cups may be secured on the same wheel hub diametrically opposite from each other. In consequence cheer the other of said cups is certain to lie above the axis of the shaft when the wheel comes to rest and as a result, the lubricant contained in the cup flows outwardly from the tube d to the hearing. The quantity thus deliv- 1 ered as well as the rate of discharge may be varied by varying the bore through the nipple. 4

Of course it is not essential that two cups be employed on the same hub as evidently one may be employed. In that event the wheel if properly balanced 1 10 Correction in Letters Patent No. 863,878.
